Reviewed August 7, 2026 · Kratom (Mitragyna speciosa). The FDA states kratom is not lawfully marketed in the US as a drug, dietary supplement or food additive, and warns consumers not to use it.
Visit Kingdom Kratom WebsiteOverview
Kingdom Kratom has operated since 2017, manufactures in San Antonio, Texas, and sells leaf powder, capsules and concentrated extracts. Before anything else, the regulatory position needs stating plainly, because the company will not state it for you: the FDA warns consumers not to use kratom at all, citing risk of liver toxicity, seizures and substance use disorder, and has determined that kratom is adulterated as a dietary supplement under section 402(f)(1)(B) of the FD&C Act and an unsafe food additive under section 409. It is not lawfully marketed in the United States in any category. Around 1.7 million Americans aged 12 and over used it in 2021 regardless, so the practical question for anyone already buying is which vendor is least bad — and on that narrower question Kingdom Kratom does better than most. It is an American Kratom Association GMP qualified vendor, publishes third-party certificates of analysis per batch covering alkaloid content, heavy metals, salmonella, E. coli and yeast/mould, and its shipping restrictions page is the most honest document of its kind we found: it names every banned state, explains that Ohio permits plain leaf powder but not capsules, extracts, shots or anything containing 7-OH under a Board of Pharmacy rule, and flags New York's 21-and-over requirement with age verification at checkout. Most notably, it refuses to spike products with isolated or synthetic 7-hydroxymitragynine and says so repeatedly — 'High 7-OH products are not natural kratom, and we're not interested in making them.' That matters, because 7-OH is a minor alkaloid comprising under 2% of natural leaf content but with mu-opioid receptor potency substantially greater than mitragynine and greater than morphine, and the FDA now runs a dedicated campaign on concentrated 7-OH products. Taking the right side of that argument is the strongest thing here. The extracts are the weakest. A single 175mg shot is, by the company's own description, the alkaloid equivalent of 12 to 14 grams of powder, at a time when the FDA notes regular users self-report under 6g per consumption. Concentration removes the natural brake that bitter, bulky powder imposes on dose.

Consultation Process
Check whether it is legal where you live
Kingdom Kratom cannot ship any kratom to Alabama, Arkansas, California, Connecticut, DC, Indiana, Louisiana, Vermont or Wisconsin. Kansas and Tennessee bans took effect 1 July 2026. Ohio takes plain leaf powder only. New York requires 21+.
Start with plain leaf, not extract
Powder and capsules carry the natural alkaloid profile. Extracts concentrate it by an order of magnitude and are where dose-related problems concentrate too.
Weigh it
Teaspoon estimates are unreliable because grind density varies. The company sells a $9.99 digital scale, and using one is the single most useful safety step available.
Understand the dependence risk before you build a habit
The FDA documents tolerance, cravings and withdrawal in kratom users meeting substance use disorder criteria. Daily use is how that starts. Bulk kilo pricing makes daily use cheap.
Eligibility
- Adults only; 21+ in New York
- Not shippable to Alabama, Arkansas, California, Connecticut, DC, Indiana, Louisiana, Vermont, Wisconsin, Kansas or Tennessee
- Ohio: plain leaf powder only
- NOT for use in pregnancy — the FDA documents neonatal abstinence syndrome after prenatal exposure
- Not for anyone with liver disease or taking hepatotoxic medication
- Not for anyone in recovery from opioid use disorder without medical supervision
- Not to be combined with opioids, benzodiazepines, alcohol or other sedatives
Provider Involvement
None. There is no clinician, no screening and no medical oversight of any kind. Nobody is checking your liver function, your other medications or your history of substance use before selling you a kilo.
Lab Requirements
None offered or required. If you use kratom regularly, periodic liver function testing is worth discussing with a doctor — the FDA's warning specifically names hepatotoxicity.
Pharmacy Fulfillment
Manufactured in what the company describes as an FDA-registered facility in San Antonio, Texas, with American Kratom Association GMP qualification and third-party batch testing. Two caveats: FDA facility registration is an administrative listing, not approval of anything produced there — and the FDA's position is that kratom cannot be lawfully marketed at all. AKA GMP is a trade-association programme run by the industry's own advocacy body; it is a meaningful quality signal relative to unqualified vendors, but it is not government oversight.

State Availability
Kingdom Kratom publishes an unusually clear restrictions page. No kratom ships to Alabama, Arkansas, California, Connecticut, District of Columbia, Indiana, Louisiana, Vermont or Wisconsin. Kansas and Tennessee bans took effect 1 July 2026 — the page still frames these as forthcoming, so it needs updating, though the underlying facts are right. Ohio receives plain dried-leaf powder only: capsules, extracts, shots, gels, liquids, 'enhanced' products and anything containing 7-OH are excluded under a Board of Pharmacy rule. New York orders are age-verified at 21+. Local county and city bans exist beyond these state rules.
Pros
- Refuses to spike products with synthetic 7-OH, and says so on nearly every product page
- American Kratom Association GMP qualified vendor
- Third-party COA per batch covering alkaloids, heavy metals, salmonella, E. coli and yeast/mould
- The clearest state-by-state shipping restriction page we found in this category
- Ships plain leaf only to Ohio, correctly following the Board of Pharmacy rule on extracts and 7-OH
- Age-verifies New York orders at 21+, per state law
- Sells a $9.99 digital dosing scale — accurate measurement is genuine harm reduction
- Advises new extract users to take half a bottle and wait 45 minutes
- No-questions-asked money-back guarantee, free shipping over $75
Cons
- The FDA warns consumers not to use kratom at all: liver toxicity, seizures and substance use disorder
- Extract shots reach 175mg mitragynine — the company's own '12-14g of powder' equivalent, against typical use of under 6g
- Kilo pricing at roughly $0.12/g makes bulk buying of a dependence-forming substance cheap
- Product copy makes mood, sleep, relief and focus claims the FDA says cannot lawfully be made
- 'FDA-registered facility' means registered, not approved
- AKA GMP is an industry trade-association programme, not government oversight
- The shipping page still describes the Kansas and Tennessee bans as upcoming; both took effect 1 July 2026
Who Kingdom Kratom May Be Best For
- People who have already decided to use kratom and want a vendor that tests, discloses restrictions and refuses 7-OH spiking
Limitations
- The FDA advises against using kratom at all
- Extract potency far exceeds typical consumption doses
- Dependence, tolerance and withdrawal are documented
- Unlawful to market as a supplement or food, yet sold with supplement-style claims
- Banned in a growing list of states
Reputation & Trust
This rating splits cleanly in two. As a kratom vendor, Kingdom Kratom is among the more responsible operators we have examined: AKA GMP qualified, manufacturing in Texas, third-party COAs per batch covering alkaloids, heavy metals, salmonella, E. coli and yeast/mould, a money-back guarantee, and a shipping restrictions page that is genuinely more informative than most companies' legal pages — it explains Ohio's leaf-only rule and New York's 21+ requirement rather than quietly refusing the order. Its position on 7-OH is the strongest point in its favour: it refuses to spike with isolated or synthetic 7-hydroxymitragynine and tells customers to avoid vendors who do. Given that 7-OH is a minor natural alkaloid, under 2% of leaf content, with mu-opioid potency exceeding both mitragynine and morphine, and that the FDA now runs a dedicated 7-OH campaign, being on that side of the line is meaningful. Selling a $9.99 dosing scale and telling extract buyers to take half and wait 45 minutes are small, real acts of harm reduction. As a product, though, the FDA's position is unambiguous and the site never mentions it: consumers are warned not to use kratom, citing liver toxicity, seizures and substance use disorder, with documented tolerance, cravings, withdrawal and cases of neonatal abstinence syndrome. Kratom is not lawfully marketed in the US as a drug, supplement or food. Against that, the product copy promises 'all-day energy and mood elevation', 'relief', 'sleep support' and 'stress relief' — claims the FDA has consistently taken enforcement action over. And the extracts cut against everything else the company does well: a 175mg shot is by its own reckoning 12 to 14 grams of powder in a 10mL vial, against typical self-reported use under 6g. Concentration is what turns a self-limiting bitter tea into something you can overdose on casually.
What Makes Kingdom Kratom Different
- Explicit, repeated refusal to spike with synthetic 7-OH
- AKA GMP qualified with per-batch third-party testing
- The most transparent state restriction page in the category
- Sells a dosing scale and gives extract go-slow advice
Our Verdict
Kingdom Kratom gets 2.5/5, and the number is doing two jobs. Judged as a business, it is one of the more responsible vendors in a poorly governed category: AKA GMP qualified, manufacturing in San Antonio, third-party COAs per batch for alkaloids, heavy metals, salmonella, E. coli and yeast/mould, a money-back guarantee, free shipping over $75, and a state restrictions page more informative than most companies' legal terms. Its stance on 7-OH is genuinely creditable — it refuses to spike with the isolated alkaloid and tells customers to avoid vendors who do, which is the right side of the biggest safety question in kratom right now. Selling a $9.99 scale and telling extract buyers to halve the dose are small acts of real harm reduction. Judged as a product, none of that changes the FDA's position, which the site never mentions: consumers are warned not to use kratom at all, over liver toxicity, seizures and substance use disorder, and it cannot be lawfully marketed here as a drug, supplement or food. The extracts undercut the company's own care — 175mg in a vial, its own '12-14g of powder', against typical use under 6g. If you have already decided to use kratom, this is a better place to buy it than most. That is the most we can honestly say.

Frequently Asked Questions
What does the FDA actually say about kratom?
That you should not use it. The FDA warns consumers against kratom because of the risk of serious adverse events including liver toxicity, seizures and substance use disorder, and notes documented cases where users met SUD criteria — using more than intended, cravings, tolerance, continuing despite harm, and withdrawal on stopping. It has recorded neonatal abstinence syndrome in newborns following prolonged prenatal exposure, and has warned about kratom products contaminated with salmonella and concerning levels of heavy metals. Legally, the agency has determined kratom is adulterated as a dietary supplement under FD&C section 402(f)(1)(B) and an unsafe food additive under section 409, meaning it is not lawfully marketed in the US as a drug, supplement or food. None of this appears on Kingdom Kratom's site.
What is 7-OH, and why does Kingdom Kratom keep mentioning it?
7-hydroxymitragynine is the issue currently dividing this industry, and Kingdom Kratom is on the better side of it. It occurs naturally in kratom leaf but only as a minor alkaloid — under 2% of total alkaloid content — while being substantially more potent at the mu-opioid receptor than mitragynine, and more potent than morphine. Some vendors add isolated or synthetically produced 7-OH to make products feel stronger, which produces something far removed from leaf kratom. The FDA runs a dedicated campaign on these products. Kingdom Kratom states across its range that it never spikes with 7-OH and that customers should avoid vendors who do. Ohio's Board of Pharmacy now bars any 7-OH-containing product from the state, which the company's shipping page correctly reflects.
How strong are the extracts compared with powder?
Much stronger, and this is where we would urge caution. By Kingdom Kratom's own descriptions, a Kingdom Burst stick pack contains 100mg of mitragynine, 'equivalent to 7-8g of kratom powder'; the Formula 2 shot is around 150mg or '10-12g'; and the Xtreme shot is 175mg, 'the equivalent of 12-14g of powder' — in a 10mL vial you drink in seconds. For context, the FDA notes that regular kratom users self-report consuming under 6g of botanical kratom per use. So a single shot can exceed twice a typical dose with none of the natural limits that bitter, bulky powder imposes. The company does advise new extract users to take half a bottle and wait 45 minutes, which is the right guidance. If you use kratom, plain leaf is the more controllable form.
Where can't they ship?
Kingdom Kratom cannot ship any kratom to Alabama, Arkansas, California, Connecticut, the District of Columbia, Indiana, Louisiana, Vermont or Wisconsin. Kansas and Tennessee bans took effect on 1 July 2026 — worth noting that the company's page still describes these as upcoming, so it is behind on maintenance even though the facts are correct. Ohio can receive plain dried-leaf powder only; capsules, extracts, shots, gels, liquids, 'enhanced' products and anything containing 7-OH are excluded. New York permits sales to 21 and over only, and orders there are age-verified at checkout. Various counties and cities impose their own bans on top of state law.
Is AKA GMP certification meaningful?
Somewhat, with an important qualification. The American Kratom Association's GMP Qualified Vendor programme involves third-party audits against manufacturing standards, and a qualified vendor is a better bet than an unaudited one — in a market where roughly 15 to 25% of imported kratom fails microbial testing, that is not nothing. But the AKA is the industry's own advocacy organisation, not a regulator. Its programme is a trade-association standard, not government oversight, and it cannot make a product the FDA considers unlawfully marketed into an approved one. Read it as a relative quality signal among kratom vendors, not as safety approval.
Can kratom help me get off opioids?
This is one of the most common reasons people use it, and it is the reason to be most careful. Mitragynine acts on the same mu-opioid receptors, which is why it can blunt withdrawal — and also why the FDA documents tolerance, cravings, dose escalation and a withdrawal syndrome of its own. Substituting an unregulated, untested-for-efficacy opioid agonist for a regulated one, without medical supervision, is a genuine risk rather than a harm-reduction strategy. Buprenorphine and methadone are approved treatments for opioid use disorder with substantial evidence behind them, and they are available via telehealth in much of the US. If this is why you are here, speak to a clinician.
Important Notes & Warnings
- The FDA warns consumers NOT to use kratom, citing liver toxicity, seizures and substance use disorder.
- Kratom is NOT lawfully marketed in the US as a drug, dietary supplement or food additive.
- Kratom acts on mu-opioid receptors. Tolerance, cravings, dose escalation and withdrawal are documented.
- NEVER combine kratom with opioids, benzodiazepines, alcohol or other sedatives — deaths have most often occurred in combination with other drugs.
- Do NOT use in pregnancy. The FDA has documented neonatal abstinence syndrome in newborns after prenatal exposure.
- Avoid entirely if you have liver disease or take hepatotoxic medication. Discuss periodic liver function testing with a doctor if you use it regularly.
- Extracts are far stronger than powder — a 175mg shot is described by the seller as equivalent to 12-14g of powder, against typical use under 6g.
- Contaminated kratom has caused salmonella outbreaks and heavy metal exposure. Buy only lot-tested product and check the COA.
- Illegal in Alabama, Arkansas, Indiana, Vermont, Wisconsin, DC and elsewhere; Kansas and Tennessee bans took effect 1 July 2026. Local bans also apply.
- If you are using kratom to manage opioid withdrawal, speak to a clinician — buprenorphine and methadone are approved treatments with real evidence behind them.
